Why Choose RIGA XL?
- The RIGA XL Greenhouse is designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sunrooms, pavilions, pool covers, home additions, and commercial building, with 28 years experience.
- With a combination of strong materials and durable hardware, the RIGA XL Greenhouse is an exceptionally strong greenhouse.
- The RIGA XL Greenhouse offers more window and door ventilation than other units in its class.
- The 16mm triple-wall polycarbonate glazing on the RIGA XL Greenhouse is German-made and believed to be of superior quality than the much more common Polygal or GE glazing.
- One major advantage of the RIGA XL's construction method is that the frame profiles are permanently attached to each other, and won't come loose over time due to wind pressures.
- German engineering - guaranteed top quality!
- Optional Shelving: Seedtray/Bench shelf and top shelf are available with strong diagonal support braces – can hold a 160 pound man! Twin-wall polycarbonate shelf inserts can be removed to allow for tall plants such as tomatoes or beans or to allow insertion of heavy-duty seed trays. This greenhouse can flex to your gardening needs throughout the year.
- The RIGA XL Greenhouse is attractive and beautiful to look at – fits well in to an upscale garden setting.
- Buying a greenhouse is like buying a car, they vary in cost from cheap to very expensive, the RIGA XL is a class similar to a Volkswagen/Volvo – stronger, more durable and better insulated, and offers many more features than the better selling brands.
- The RIGA XL Greenhouse offers the insulation needed to grow plants year-round – others using less insulation cost too much to heat.
- RIGA XL Greenhouse units are available in 5 sizes.
- We recommend you buy one size bigger than you planned.

- Riga XL
Great product and best support I've ever seen
I looked for a large greenhouse for a year. My wife and I choose the Riga XL because of the size and style. Best of all, we are super happy with the quality of the greenhouse and the support we got from Andrew and his team. I'm 63 and my wife is a little younger. We were able to put it together by ourselves with the great advice we got from Andrew. It took time, and at times was a little frustrating, but it was well worth it. When we ran into problems, Andrew solved the problems quickly and without question about whose fault it was. If I were to buy another greenhouse, The Riga and Andrew would be my first and only choice.
